Description
Technical Field
The utility model relates to a check out test set technical field, in particular to mud concentration detection control system.
Background
The sludge concentration, i.e. the milligrams of net weight of the suspended and mixed dry sludge per unit volume, is mainly used in the sewage treatment process, and the solid content of the index is approximately 10: 1. At present, the tail water treatment process section of the domestic water works lacks a reliable detection means for the sludge concentration of the sludge discharged from the concentration tank, and the sludge discharge time is controlled by manual experience. Too long sludge discharge time can cause sludge water with sludge concentration lower than 3000mg/L to enter the balancing tank, so that the solid content of the balancing tank is too low, and the cost of chemical consumption and power consumption for sludge dehydration is increased. The common pipeline type ultrasonic sludge concentration meter is inconvenient to disassemble, clean and maintain.
Disclosure of Invention
The utility model aims at overcoming the defect that prior art exists, providing a sludge concentration detection control system.
Realize the utility model discloses the technical scheme of purpose is: a sludge concentration detection control system comprises a sludge collection container, a sludge concentration meter, a control valve group and a water inlet pipe; the water inlet has been seted up on mud collection container top, and the delivery port has been seted up to the side, the water inlet intercommunication has the inlet tube, be provided with the mud densimeter on the top of mud collection container, be provided with the valve unit on the inlet tube.
Furthermore, the control valve group comprises an electromagnetic valve and a manual ball valve, and the electromagnetic valve is controlled by a PLC control cabinet electrically connected with the outside.
Further, the outside cover of mud concentration meter is equipped with the PVC protective sheath, fixes on the top of mud collection container.
Further, the bottom plate of the sludge collection container is arranged to be an inclined surface inclined towards the water outlet.
Furthermore, a flow guide inclined plate is arranged on a bottom plate of the sludge collection container below the water inlet.
Furthermore, a support is fixed at the bottom of the sludge collection container.
After the technical scheme is adopted, the utility model discloses following positive effect has:
(1) The utility model has simple installation and convenient maintenance; the sludge collection container has a simple structure and is easy to process. Can be constructed and installed on line without stopping production.
(2) The utility model discloses utilize PLC control technology, the mud concentration that can the accurate control row mud.
Drawings
In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in figure 1, the utility model is provided with a sludge collection container 1, a sludge concentration meter 2, a control valve group 3 and a water inlet pipe 4; the water inlet 11 has been seted up on 1 top of sludge collection container, and delivery port 12 has been seted up to the side, and water inlet 11 communicates has inlet tube 4, and inlet tube 4 comprises DN50 steel pipe and 90 elbows, is provided with mud concentration meter 2 on the top of sludge collection container 1, is provided with the valve unit 3 on the inlet tube 4. The control valve group 3 comprises an electromagnetic valve 31 and a manual ball valve 32, and the electromagnetic valve 31 is controlled by a PLC control cabinet electrically connected with the outside and used for controlling the on-off of the sampling pipeline. The manual ball valve 32 is used to control the flow rate.
The outside cover of mud concentration meter 2 is equipped with the PVC protective sheath, fixes on the top of mud collection container 1. The PVC protective sleeve 21 is used for preventing the probe of the sludge concentration meter 2 from rubbing with the stainless steel plate and fixing the probe. The probe of the sludge concentration meter is inserted into the container through the protective sleeve.
The bottom plate of the sludge collection container 1 is arranged to be an inclined surface inclined towards the water outlet 12. The sludge sample can flow conveniently, and a bottom plate of the sludge collection container 1 below the water inlet 11 is provided with a diversion inclined plate 13. And an emptying groove 15 with the width of 4mm is formed at the junction of the bottom plate and the flow guide sloping plate 13 for emptying the mud sample. A bracket 14 is fixed at the bottom of the sludge collection container 1.
The utility model discloses a theory of operation does:
the utility model discloses the during operation, PLC switch board at first starts into the dredge pump, because of the mud concentration of advancing at this moment is more dense, need not the sampling, after 5 minutes when arranging mud in succession, opens solenoid valve 31, and the flow that mud appearance was established according to manual ball valve 32 gets into mud collection container 1, PLC measures mud concentration, closes into the dredge pump when 5 seconds average mud concentration in succession is less than 3g/L, closes solenoid valve 31, advances mud and finishes.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
